SPECIFICATION forming part of Letters Patent'No. 532,607, dated January15, 1895.

7 Application filed October 28, 1891- Serial No. 419,076. (No model.) i

To aZZ whom it may concern:

Be it'known thatI, STEFAN STEINMETZ, of Leipsic-Gohlis, in the'Kingdom.of Saxony, German ghave invented an Improved. Decorticating andScouringMachine, of which thefollowing is a specification.

This. invention relates to a machine for removing the bran frommoistened grain and for simultaneouslydrying and polishing the kernels,by one continuous operation. The grain admitted at one end of themachine is subjected to the action of a series of disks and intermediatepressure blocks. From these the grain is thrown up by scoops and anexhaust to fall upon an' oblique guide or deflector which conducts thegrain from one of the disks to the next adjoining disk or disks. Herethe action is repeated and in this manner the grain is made to traverselaterally the entire machine. .Thus the grain is thoroughly spread andis repeatedly subjected to the action of the air current to be properlydecorticated,'dried and polished.

In the accompanying drawings: Figure 1 is a longitudinal section of themachine; Fig. 2,

an end View thereof; Fig. 3, asection onlineR, B, Fig. 1; Fig. 4, asection on line S, S, Fig. 1; Fig. 5, a horizontal section on line T, T,Fig. 4. Figs. 6 to 8, are details of the pressure blockB; Fig. 9, avertical cross section of a modification of the machine; Fig. 10, ahorizontal section on line U, U, Fig. 9; Fig. 11, a face view of thedeflector D. Figs. 12 to 15 are details of the exit gate; Fig. 16, avertical cross section of a further modification of the machine; Fig.17, a section on line M, M, Fig. 16; Fig. 18,a section on line N, N Fig.

' 16; Fig. 19, an end view partly in section of the machine; Fig. 20, aplan of Fig. 19; Fig. 21, a vertical longitudinal section thereof. Figs.22 to 24 are details of the scoop F.

In Figs. 1 to 8, the letter a, represents a shaft driven from a suitablepulleyyand provided with a series of disks A, mounted upon the shaft ateven distances apart. The disks are provided with shovels and betweenthe disks there are placed decort-icating pressure blocks B, that bearagainst the disks to subject the grain to a proper pressure. Each blockB, is

composed of a pair of jaws d, hinged together .at one end and divergingtoward the other end; To the freeends of the jaws d, are secured theinwardly projecting wedge shaped cheeks d, that may be spread to asuitable extent by an intermediate spreader block b. This block isvertically adjustable by a lever O, to which it is connected and thatcarries a sliding counterweight 0'. Thus it will be seen, that thedegree of force with which the blocks B, bear against the disks A, maybe readily adjusted.

The grain is admitted bya hopper at one end (left end) of the machineand on falling upon the nearest disk is acted upon by the same, afterwhich it is thrown up by the shovels and the air blasts or vane E. Thegrain thus thrown up is intercepted by stops 0, that permit the dust topass up, while the heavier acted upon in the same way, as it has beenacted upon by the first disk. In this way the grain traverses the entiremachine to be acted upon by allthe disks and to be repeatedly spread andsubjected to the air currents, after which it is discharged by gate K.

In Figs. 9 to 13, I employ two shafts a, a, provided with alternatingdisks A, and driven toward each other. Here the pressure blocks aredispensed with, and the disks are made tapering or lens shaped so as tosnugly fit against each other. The guide D, is placed at the sides ofand. below the disks, and the grain is conducted into the channels bymeans of deflectors h, which can be laterally inclined. The grain isdischarged by a door or lid K, counterbalanced by weighted lever g, thatnormally holds the door in its upright or closed position. On its innerside the door K,-is provided with a number of inclined wings 70. Againstthese Wings the grain is blown and when the pressure is sufficient toovercome the weighted arm g, the door will open to permit the escape ofthe grain. In this way the door will not open until the machine is infull operation.

In Figs. 16 to 24, each disk A, is composed of two tapering rings Z,connected by pins Z, to which the oblique shovels F, are attached. Belowthe disks there is placed a perforated jacket M, and the rotation of thedisks and shovels will cause air to be drawn up through this jacket.These shovels will also force the in through the grain and cause thelateral motion of the grain along the bottom of the machine. Thus grainand disks are properly cooled and the former is thoroughly cleaned andseparated from the bran and dust that is drawn out by the exhaust. Thedisks may be either separatelyorcollectivelysurrounded by the jacket.

Between the disks A, there are placed the blocks L, secured by arms f,to the rods m. These rods are free to turn in a cross piece H, and areprovided at the ends with levers n, carrying the adjustable weights J,or they are acted upon by springs N. Thus the pressure of blocks L,against the disks A, can be readily adjusted. The grain on being thrownup, is deflected by the cross piece H, and is made to traverse themachine in the manner described. The waste is drawn oif by exhaust O.

The blocks L, cause a uniform action upon the grain, independent of thequantity fed into the machine as when set, the blocks will automaticallyregulate the pressure.

What I claim is- 1. The combination of a shaft with a series of disksmounted thereon laterally expanding pressure blocks that bear againstthe sides of the disks and an inclined guide, for feeding the grain fromone disk laterally to the following disks, substantially as specified.

2. The combination of a shaft with aseries of disks mounted thereon, aninclined guide having channels for feeding the grain in a lateraldirection, laterally expanding pressure blocks that bear against thesides of the disks and ablower, substantially as specified.

3. The combination of a shaft with a series of disks mounted thereon, agrooved guide, adjustable deflectors h, and with weighted door K, havingwings is, substantially as specified.

4. The combination of a shaft with a series of disks mounted thereon andcomposed of the tapering rings Z, and with the connecting pins Z, andthe inclined shovels F, secured thereto, substantially as specified.

5. The combination of a shaft with aseries of disks mounted thereon andwith pressure blocks L, arms f, rods m, cross piece H, and weightedlevers N,'snbstantially as specified In testimony whereof I have signedmy name to this specification in the presence of two subscribingwitnesses.
